kuyang'anira chilengedwe cha nkhumba.
Kutentha ndi chinyezi pa chonde
Ndizodziwikiratu kuti kutentha kwakukulu ndi chinyezi kumapangitsa kuti nkhumba zichedwetse estrus pambuyo poyamwitsa.
Kutentha kukadutsa 22 ℃, zofesa zimayamba kukumana ndi kutentha, zomwe zimalepheretsa.
kutulutsa kwa timadzi ta luteinizing ndipo kumabweretsa kusakwanira katulutsidwe ka follicle stimulating hormone
(FSH) ndi timadzi ta luteinizing (LH), zomwe zimapangitsa kuti ma follicular akule bwino, oocyte yachilendo.
morphology, kuchedwa kutulutsa ndi kuchepa kwa dzira mu nkhumba zoweta, zomwe zimapangitsa kuchepa kwa zinyalala.
Hengko's nkhumba chilengedwekuwunika kutentha ndi chinyeziyankho adzakupatsani kutentha
ndi data kusintha chinyezi, ndipo mukhoza kupanga miyeso kusintha chilengedwe kutentha ndi chinyezi
kuzungulira nkhumba molingana ndi kusintha kwa data.
Mu 2002, He Yongjun adasanthula kulumikizana kwachilengedwe pakati pa kuchuluka kwa chonde komanso kutentha ndi chinyezi.
pafamu yaikulu ya nkhumba mumzinda wa Zhongshan ndipo anapeza kuti kutentha kukakhala kokwera, kumachepetsanso kubereka,
ndipo kutentha kunali ndi mphamvu zochepa pa mlingo wa chonde, pamene kutentha kwakukulu ndi chinyezi chachikulu
anali ndi chikoka chachikulu pa mlingo wa chonde.Mu 2004, Hu Songen adamaliza kafukufuku wokhudza kutentha
ndi chinyezi pafamu yayikulu ya nkhumba ku Foshan, m'chigawo cha Guangdong, ndipo zotsatira zake zidawonetsa kuti potentha
chilengedwe cha 27.1-29.3 ℃, mlingo wa estrus wa nkhumba 15d pambuyo pa kuyamwa unali wotsika kwambiri kuposa
mlingo wofanana wa estrus m'malo otentha a 17.7-20.4 ℃.
Kutentha kwakukulu m'chilimwe kumalimbikitsa kuswana kwa mavairasi osiyanasiyana ndi mabakiteriya, omwe amatha kutuluka mosavuta
matenda osiyanasiyana, monga uchembere ndi kupuma syndrome, amene angayambitse mwachindunji
zizindikiro monga kuchotsa mimba ndi kubala nkhumba.Mafamu ambiri a nkhumba amagwiritsa ntchito madzi pansi kuti akwaniritse zotsatira zake
kuziziritsa, koma kwenikweni, kutuluka kwa kutentha kwakukulu kumapangitsa chinyezi chamlengalenga kukhala chachikulu, komanso
kutentha ndi chinyezi m'khola la nkhumba zokhala ndi malo osakwanira zimakula kwambiri, zomwe zimapangitsa kuti nkhumba zikhale zotsika kwambiri, r.
ophunzitsidwa kukula zinyalala, ndipo ngakhale kubuka kwa matenda opatsirana, chifukwa mu ubereki matenda.Lu Wei adanenanso
kuti pafamu yoweta yoyambirira ku Jiangxi, kuchuluka kwa estrus kwa nkhumba mu Julayi-Seputembala mkati mwa 7d pambuyo poyamwitsa
anali 70.6% okha ndi hyperthermia, ndipo chonde chinachepetsedwa kufika 50% mu March, pamene chiwerengero cha estrus cha nkhumba.
mu chomera ichi mu December-February anali 97,7%.Ambiri amavomereza m'makampani kuti kukula kwa zinyalala kumakhala
apamwamba kwambiri mu Marichi-Meyi ndi Disembala chaka chilichonse, pomwe amakhala otsika kwambiri mu Ogasiti, ndipo kuswana kwachisanu ndikwabwino kuposa
nyengo zina zitatu.Liu Yu et al.anaunika kafukufuku m'dera Guangdong ndipo ananena kuti pafupifupi
Kukula kwa zinyalala za nkhumba zomwe zimakwerana mu gawo lachinayi zinali zapamwamba kwambiri ndipo pafupifupi zinyalala za nkhumba zomwe zimakwera mu
Gawo lachiwiri linali lotsika kwambiri.
Nkhumba zokhala ndi kutentha kwa nthawi yayitali zinali ndi chilakolako chogonana chochepa, kuchepetsa kudya, kuchepa kwa umuna,
komanso kuchuluka kwa kusasinthika kwa umuna, zomwe zidakhudza kwambiri umuna.Pambuyo pophunzira zotsatira za
kutentha pa ntchito ya umuna wa nkhumba, Hansen Park inanena kuti umuna ntchito sanali anakhudzidwa mkati 24h
pafupifupi 24 ℃, koma pang'onopang'ono udatsika ndikuwonjezeka kutentha pamwamba pa 24 ℃.Kupsinjika kwa nkhumba kutentha ndi
kuzizira ndi mbali yomwe imakhudza chonde cha nkhumba.Kuchuluka kwa ana a nkhumba asanakwanitse masiku 20 akubadwa mu 0-10 ℃
Kutentha kumakhala kocheperako kuposa komwe kumakhala 20-35 ℃ chifukwa chosakwanira
kukula ndi kusakwanira kwa kutentha kwa ana a nkhumba akabadwa.
Njira zothanirana ndi zinthu zobisika za kutentha ndi chinyezi
Kutentha ndi chinyezi ndi mavuto omwe amapezeka m'mafamu onse a nkhumba koma amanyalanyazidwa mosavuta.
Mutha kugula a Hengkomita kutentha ndi chinyezikuyang'anira kutentha ndi chinyezi cha

mashedi okhala ndi mikhalidwe ayenera kuyikidwa ndi ma air conditioners kapena okhala ndi zofananira
zida zotenthetsera kuti zifulumizitse mpweya wabwino ndi kuziziritsa, komanso minda yayikulu ya nkhumba nthawi zambiri
kutengera denga fan kuziziritsa 2-3 anafesa.M'nyengo yozizira, ozizira-umboni ndi ofunda ntchito wakhanda piglets
kuyenera kulimbikitsidwa kuti tipewe nkhanza zomwe zimachitika chifukwa cha kuzizira kwa ana a nkhumba.
